This invention relates to certain novel improvements in slicing machines andconsists of a construction that may be readily asso= ciated with a suitable container in which the article to be sliced may be stored.

The salient object of my invention is to provide a container, adapted to receive a loaf of bread or the like, which will be arranged so as to embody a device for slicing the bread 19 or the like. Y i

obj ct, anci lary to the foreg ing, is t ge e con ainer in such amanner at i may h s d so as to pr te t the br or other material stored therein.

.15 Another object of the invention is to so arrange the container that the bread may be fed forward to the slicing means in an automatic and continuous manner.

A still further object of-the invention is to so arrange the device that the thickness o the por i ns liced r m he. oaf may e varied A still furtherobjeot ofthe invention is to so construct a device of the ioregoing char- 2 act'er that it will be economical in construct n nd simple nd fii ient i ope ati n- Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be here'- 3? ina-fter' described and claimed.

' The invention will be best understood by referenc to he ac ompany ng awings,

' showing the preferred forniof construction and in which:

.1 1 Fig. 1 is a longitudinalseo nal v ew o e .picting a preferred form of construction for my in e tion; 7 r 7 Fig. 2 is a transverse sectional view taken substantially on the line 2-2 of Fig. 1-; P a F g- 3 is a ieW king in a th ight hand end of Fig.1; f v

Fig. 4 is a sectional detail view taken sub stantially on the li eM of Fig. 3; and

Fig, 5 is a secti nal. de i w en sub stantially on the line 51-5 on Fig. 1.

In the drawings wherein I have illustrated a prefe red em odimen of my invention, 10 indicates acont in r having an open pp id os y the hing d li 11, itl id b ng connected. to said bo y 1.0 by any. suit l hinge structure such as that indicated by 12 in the drawings. 1 i e At one end of the body 10 an outstanding lip portion 13 is provided'which includesa foot portion 1a disposed parallel to a flange 15 provided on the'body portion 10.. The bolt and nut constructions 17 are provided which hold the foot portion 14 in association with the flange 15 and spacing washers. 18

are disposed between said portions 141 and 0 hereinafter. v a

A door 19 is provided which is pivotally attached to the lip 13 in any approved mall ner such as the pintles indicated at 20 in the 6?; drawing. The door 19 is disposed around 15 having a purpose to be brought forth ,the lip 13 in order to close this forward end of the housing 10 as is indicated in dottedlines on Fig. 1. When the door 19 is moved from closed position it isdisposed in the full i line position shown in Fig. 1 and serves as a receiving member for the portions sliced from the material mountedin the housing 10.

In the botto n'wall 21 of the housingld adjacent the frontend of the device an open- 5 ing 22 is provided. Depending ears 23' are secured 'to therunder sideof the wall 21 and rotatably support a groove pulley 2i as is clearly illustrated in Fig. 5.." ,A Slide 251s provided which includes upstanding porf tions 26 on which thepiercingportion 2'? is mounted, said piercingportioir being diss posed parallel to. the wall 21. vIn the wall Zladjacent the rear endoi the housing 10, I a headed screwi28 'is mounted. 'An opening 55 29 is provided in the slide 25. which is of size suificient to permit vpassagecf the head of the screw 28. .In a rnannerflto bebroughtj forth hereinafter, theslide 25 is-held in a forwardly'position so as. to dispose the edge portion around the opening'29 under the head bfscrew 28 P t m vem nt of the slide Iltil the same is detached frorn th screw 28;

As is clearly jillustrated Fig. 1; a suit able leg. structure 30 is adapted to support the h sing 10 in h a manner as to space the wall 21 froin the member on which .the-

container. isn ounted. A- bracketfil i s mo d on the re war ly di po ed Iegeen 100.

structions 30 below the wall 21 and a pulley 32 is rotatably mounted in this bracket. A coil spring 33 is directed around the pulley 32 and one end thereof is detachably connected to the forwardly disposed leg construction 30 as indicated'at 34. The ope posite end of the spring 33 is connected to a cable 35 that is suitably directed around the pulley 24 and which extends along the upper side of the wall 21 and which is suitably connected to the slide 25. This con- V struction causes the hereintofore mentioned 7 be varied.

forwardly urged movement of the slide 25 which is limited by engagement of said slide 7 In'operation, a loaf of bread or the like indicated by B in the drawings; is so mounted in the container that the piercing element 27 will enter the rear end thereof. By releasing the slide from the screw 28 the spring 33 tends to urge the slide25 forwardly and thus force the loaf of bread B forwardly into engagement. with the tongue 38 which limits forward movement thereof. v

Inthe flange 15 and the foot portion 14 which are vertically disposed'on one side of the device, aligned openings 42 are provided. It has been pointed out that the flange 15 and the foot portions 14 are spaced apart and 'betweenthese elements a suitable cutting element such as theknife 43 extends. A slot 44 f is provided in the forward end of the knife and a pin construction 45 extends through the; slots .42 and the slot 44 so as to permit 2 the knife 43 to be movedin both a horizontal 7 and a vertical plane. It isgapparentthat the loaf of bread B will extend beyond theposition of the knife 43 the magnitude of this ex-.

7 tent beingdetermined by the-position of the tongue 38. Therefore, hydra-wing the knife 43 downwardly and at the same time reciprocat-ingit'in a horizontal plane, a slice'or portion may becutfrom theloaf ofbread B which afterbeing cut will fall down into the door 19 whichewill be disposed in thefull line position in Fig. 1'. In order to prevent forv f ward movement of the loaf of bread'B until the knife 43 is'retracted to its uppermost position I mount the spring'leaf 46 on. the

under side of the lid 11 which includes a 1 foot portion 47 thatis adapted to bear against a v the loafof bread B. An opening 48 is pro-. vided in the lid 11 and the stem4c9 of the handle 50 extends therethrough, said stem 49 being suitably connected to the member 46. A suitable leaf spring 51 tends to hold the handle 50 in'its uppermost position. By depressing the handle 50 the foot portion 47 is forced into engagement with the loaf of bread 'B and thus forward movement of the loaf B is prevented until said handle 50 is released.

The arm 41 is pivotally mounted as indi-, cated at 52 and includes a formed portion 53 that is disposed in the path of the knife 43. A coil spring 54 is connected to the arm 41 as indicated best in- Fig. 3 and tends to hold said arm in the position illustrated in said Fig. 3. However, when the knife 43 passes down through the loaf B so as to cut a portion therefrom, said knife engages said formed portion 53 and thus pivots the arm 41 downwardly which retracts the tongue 38 from stopping position which facilitates the falling of the portion cut from. the loaf into the door 19. As the knife 43 is retracted a spring 54 acts to move the tongue 38 back into stopping position and when the knifev43 has attained its uppermost position the operator will release the handle 50 so as to permit the spring 33 to act through cable 35 and slide 25 to move the loaf of bread B forwardly into engagement with the tongue 38 which positions another portion of theloaf such that it may be properlycut from said loaf.

It is apparent from the foregoing that I haveprovided a device which will permit cutting so-called slices from a loaf of bread in a manner such that said slices may be of a variable uniform thickness. I have arranged the device in such a manner that it may expeditiously be closed so as to preserve the un cut portions of the loaf inafresh condition; whichis obviously an advantage and jinasmuch as theloaf is always urged forwardly" the portion will always be in cutting position.

While I have illustrated and describedthe preferredform of construction for carrying my invention into elfect, this is capable of variation and modification Without "departprecise details of constructionsetfforth, but desire to avail myself of'such variationsand modifications 1 as come within the scope of the appended claims. g Y

Having thus described my invention what I claim as new and desire to'protect by Letters Patent is: V V v lLIn adeviceof the class described, a housing'having' an open end and an open upper side, a slide in 'saidhousing adapted to bear against an article introduced into said housing through said open" upper side,v

a hinged lid forclosingsaid upper side; a .door for closinggsaid open end adapted to .ing fromthe' spirit of the invention? I,

therefore, do not'wish to be "limited to the be disposed when'in open position to serve 1 as a receiving member, spring'meansadapted to be connected to said slide whereby to urge said slide and the article carried thereby towards said open upper end, adjustable means for limiting said forward movement, cutting means including a knife adapted to be dis posed in spaced relation to said adjustable limiting means vwhereby the portion of said article between said cutting means and said 7 adjustable stop may be out from said article,

said stop including a portion adapted to be disposed below said knife whereby said stop may be retracted from limiting position, and means for holding said article against movement when said stop is retracted.

2. In a device of the character stated, a housing having an opened end, a guide mem ber arranged at said open end including portions spaced from said open end to provide a slot, a slide in said housing, means for urging said slide toward said open end whereby to force an article toward said open end, a pivotally mounted member including a portion adapted to extend into the path of said article to limit the forward movement there- 7 of, a knife adapted to act in said slot to sever a slice from said article, and means adapted to cooperate with said guide member for closing said open end and movable into a substantially horizontal position to receive a slice cut from said article by said knife.

3. In a device of the character stated, a housing having an opened end, a guide member arranged at said open end including portions spaced from said open end to provide a slot, a slide in said housing, means for urging said slide toward said open end whereby to force an article toward said open end, a pivotally mounted member including a portion adapted to extend into the path of said article to limit the forward movement thereof, a knife adapted to act in said slot to sever a slice from said article, and means adapted to cooperate with said guide member for closing said open endand movable into a substantially horizontal position to receive a slice cut from said article by said knife, said pivotally mounted member having a lug formed on one end portionqthereof adapted to extendinto the path of said knife whereby when said knife is moved-through said article to out said slice therefrom said;

knife will engage said portion and pivot said member to retract a portion thereof from the path of movement of said article, and means for normally holding said member with the portion thereof in the path of said article.

In testimony whereof I afiix my signature.
